#include <dnnl.hpp> struct desc { // fields dnnl_pooling_desc_t data; // construction desc( algorithm aalgorithm, const memory::desc& diff_src_desc, const memory::desc& diff_dst_desc, const memory::dims& strides, const memory::dims& kernel, const memory::dims& padding_l, const memory::dims& padding_r ); };

Detailed Documentation

Descriptor for a pooling backward propagation primitive.
Construction
desc( algorithm aalgorithm, const memory::desc& diff_src_desc, const memory::desc& diff_dst_desc, const memory::dims& strides, const memory::dims& kernel, const memory::dims& padding_l, const memory::dims& padding_r )
Constructs a descriptor for pooling backward propagation primitive.
Arrays
strides
,
kernel
,
padding_l
, and
padding_r
contain values for spatial dimensions only and hence must have the same number of elements as there are spatial dimensions. The order of values is the same as in the tensor: depth (for 3D tensors), height (for 3D and 2D tensors), and width.
Parameters:
aalgorithm
diff_src_desc
Diff source memory descriptor.
diff_dst_desc
Diff destination memory descriptor.
strides
Vector of strides for spatial dimension.
kernel
Vector of kernel spatial dimensions.
padding_l
Vector of padding values for low indices for each spatial dimension
([[front,] top,] left)
.
padding_r
Vector of padding values for high indices for each spatial dimension
([[back,] bottom,] right)
.
